How Often Should You Update Your Antivirus Software?

Antivirus software protects devices from various digital threats, including viruses, Trojans, ransomware, and spyware. According to the 2025 Antivirus Statistics and Consumer Report, 75% of users believe their antivirus software effectively safeguards their devices. The effectiveness of antivirus software depends on the last update, as neglecting updates leaves devices vulnerable to emerging threats. Frequent updates are necessary because hackers continuously develop new malware. Failing to update antivirus software increases the risk of hacking and can degrade device performance. It is recommended to check for updates daily, perform manual checks weekly, and expect major updates every 3 to 6 months. Free antivirus software may offer limited protection and fewer updates, requiring users to be proactive in checking for updates.

Antivirus vs Anti-malware: which is best for you?

The landscape of cyber threats has evolved, with increased sophistication and frequency of attacks, partly due to advancements in artificial intelligence. Businesses, regardless of size, should reassess their vulnerabilities as even small entities can be targeted. Investing in robust cybersecurity software is essential, with a distinction between antivirus and anti-malware tools being crucial. Malware includes various types of malicious software, and while antivirus software primarily uses signature-based detection, anti-malware tools employ advanced techniques like behavioral analysis and sandboxing. Anti-malware programs can identify hidden threats that antivirus may miss, such as rootkits. Antivirus solutions have adapted to include heuristic analysis and additional features like password management and firewalls. Antivirus is designed for average users, while anti-malware is favored by high-risk users, though everyone can benefit from both. Combining antivirus and anti-malware creates a layered security system, and many vendors now offer integrated products. Popular antivirus solutions with anti-malware capabilities include Bitdefender, Norton 360, McAfee, and Avast. Users are encouraged to run both types of software or choose a combined solution for comprehensive coverage. Despite high detection rates, users should remain vigilant and informed to reduce the risk of cyberattacks.

VPN vs Antivirus 2025: Which Protects Your Finances Better?

In 2025, finance professionals face significant cybersecurity challenges due to evolving cyber threats. A VPN (Virtual Private Network) secures internet connections and encrypts data, while antivirus software detects and neutralizes malware and phishing attempts. For optimal protection, it is recommended to use both tools. A VPN masks IP addresses, encrypts sensitive transactions, prevents data harvesting on public Wi-Fi, and shields browsing from tracking. Antivirus software detects malware, blocks phishing emails, prevents keyloggers, quarantines infected files, and offers real-time threat detection, but does not encrypt internet connections. The comparison shows that a VPN encrypts internet traffic and hides IP addresses, while antivirus software prevents phishing and malware, detects keyloggers, and provides real-time threat monitoring. For financial safety, using both a VPN and antivirus is crucial, especially when accessing sensitive data on public networks or dealing with potentially harmful downloads. Common scenarios include using a VPN for banking on hotel Wi-Fi, requiring antivirus for suspicious downloads, and needing both tools for trading crypto on public Wi-Fi. Relying on one tool alone is insufficient, as a VPN does not protect against malware, and antivirus does not secure internet traffic.

Unofficial Windows reinstaller app locks you out of your Windows 11 PC until you pay

Windows 11 version 25H2 may allow users to uninstall Microsoft apps, addressing concerns about pre-installed software. However, recent tests suggest that the impact of such bloat on performance is minimal, leading some users to reconsider the need for a cleaner system. A concerning trend involves an unofficial app called "Windows Reinstall Master," which charges users 98 RMB for reinstallation services while locking them out of their operating system. This app resembles ransomware and often installs unwanted software, counteracting users' intentions to reset their systems. The situation is exacerbated by Microsoft's upcoming end of support for Windows 10, prompting users to seek help from unreliable sources, increasing the risk of scams.

Call of Duty: WW2 on PC Game Pass yanked offline amid reports security exploits are leaving players with screens full of smut

Activision has temporarily removed the PC Game Pass version of Call of Duty: WW2 due to reports of an unspecified issue, with concerns raised about a potential remote code execution (RCE) exploit causing disruptive app pop-ups, unexpected PC shutdowns, and inappropriate content. The game is unavailable on both the Game Pass and Microsoft Store but remains accessible on Steam and Battle.net. Community feedback indicates that the game may be vulnerable to RCE exploits, allowing malicious actors to execute harmful code on players' systems. A notable incident involved streamer Wrioh, who reported being "hacked," with a video showing a pop-up claiming, "just RCE'd your ass," and a change to their desktop wallpaper. The VX-Underground malware research collective shared images of an alleged RCE attack, highlighting an "unpatched RCE exploit" and instances of trolling with pop-ups and inappropriate content. VX-Underground speculated that the attacker could deploy various forms of malware, though their primary intent seems to be creating chaos. As of now, Call of Duty: WW2 for PC Game Pass and the Microsoft Store remains offline, with no updates from Activision on its return.
